Through spacetime, which also includes space, so you're moving the space around it, essentially.
Also force doesn't require movement, since work implies movement; an infinite amount of force *technically* doesn't have to move anything.
While the stump will move slightly, it's possible that say, compressed water, won't be compressed anymore, or say, a solid chunk of iron etc.
Also an unstoppable force may not have a physical entity; thus it's "pure force"; while technically impossible, without momentum, it doesn't *technically* have to move it.
Light for instance has no mass, and thus it should have no momentum; but it does.
Gamma rays have substantially less momentum, so they're harder to make power from, while microwaves are the easiest, which is why microwaves are used to boil water inside microwaves, since it transfers energy the best, or has the most momentum. Without any momentum, however, mass or no mass, it won't actually move or, might not neccesarily move. Since none of these objects actually exist it's questionable as to what might happen or if an unstoppable force would have momentum or not; technically, an unstoppable force doesn't have to have momentum, but idk how that would work in real life, there could even be multiple types of unstoppable forces. Which is why I describe multiple scenarios. xP
